Large Language Models (LLM) & AI Market: Google renames NotebookLM to Gemini Notebook
Google renamed NotebookLM to Gemini Notebook and is expanding its integration across Google services, including the Gemini app and forthcoming access via AI Mode in Google Search. The tool—originally Project Tailwind and used by over 30 million people and more than 600,000 organizations—now makes each notebook a secure container and adds in-notebook code execution and advanced data-analysis capabilities. Those features, previously tied to Google AI Ultra and certain Workspace business plans, will roll out to Google AI Pro subscribers in the coming weeks. Separately, reports (CNBC citing Bloomberg) say the next flagship model, Gemini 3.5 Pro, is delayed by several months and prompted about a 4% drop in Alphabet shares; Google says it is testing Gemini 3.5 Pro and other models with partners but has not confirmed a launch date.
This is a technical product update and rebrand from Google — a major platform — that expands in-app AI capabilities and integrates notebooks with Gemini and Search, which can influence enterprise adoption and downstream creator and content workflows.
